Canvas graphics from TPrintPreview distorted

[borisneubert]

Hi,

a simple canvas graphics created with RoundRect and LineTo and written to PDF with SynPDF is distorted when created from a TPrintPreview.

Please find attached in SynPDFTester.zip a minimal program to reproduce the issue plus two sample PDF files to illustrate the issue: test_metafile.pdf is directly created from a canvas graphics in a metafile (correct), test_preview.pdf is created indirectly from a canvas graphics from a print preview.

I use the TPrintPreview component from here: DelphiArea which in turn uses SynPDF for creating PDF files from previews. TPrintPreview internally also uses metafiles to render and store the pages for preview. The preview on screen is right but the PDF created from the metafile is not.

Best regards,
Boris
